According to POSIX the rusage structure should be filled if it's not
NULL. Ironically, Hurd uses the wait3 implementation from
[glibc]/sysdeps/posix/wait3.c, which does not do that. Attached is
a patch to bring it to POSIX compliance.

        * sysdeps/posix/wait3.c (__wait3): Fill in the USAGE argument
        if it is not NULL. This change is required for POSIX compliance.
